Journal ArticleDOI
Opacities for stellar envelopes
TL;DR: In this article, the authors defined stellar envelopes as regions of stellar interiors in which atoms exist and are not markedly perturbed by the plasma environment and adopted the criterion of mass density ρ≤0.01 g cm −3.
Journal ArticleDOI

TL;DR: Measurements of wavelength-resolved iron opacity at electron temperatures and electron densities at the solar radiation/convection zone boundary show that wavelength-dependent opacity is 30–400 per cent higher than predicted, which represents roughly half the change in the mean opacity needed to resolve the solar discrepancy.
Journal Article
Atomic data from the IRON project. I. Goals and methods.
TL;DR: The IRON project as mentioned in this paper aims to compute electron excitation cross sections and rates of astrophysical and technological importance using the most reliable procedures currently available, e.g. from the Opacity Project.
Journal ArticleDOI
Molecular Hydrogen and [FeII] in Active Galactic Nuclei
Alberto Rodríguez-Ardila,Miriani Griselda Pastoriza,Sueli M. Viegas,T. A. A. Sigut,Anil K. Pradhan +4 more
TL;DR: In this article, near-infrared spectroscopy is used to study the kinematics and excitation mechanisms of the H2 and [FeII] gas in a sample of AGN.

Molecular hydrogen and (Fe II) in Active Galactic Nuclei
Alberto Rodríguez-Ardila,Miriani Griselda Pastoriza,Sueli M. Viegas,T. A. A. Sigut,Anil K. Pradhan +4 more
TL;DR: In this paper, the authors used near-infrared spectroscopy to study the kinematics and excitation mechanisms of H2 and (Fe ) lines in a sample of mostly Seyfert 1 galaxies.
